Detailed explanation-1: -A germline mutation occurs in a sperm cell or egg cell. It passes directly from a parent to a child at the time of conception. As the embryo grows into a baby, the mutation from the initial sperm or egg cell is copied into every cell within the body.

Detailed explanation-2: -If a parent carries a gene mutation in their egg or sperm, it can pass to their child. These hereditary (or inherited) mutations are in almost every cell of the person’s body throughout their life.

Detailed explanation-3: -If an acquired mutation occurs in an egg or sperm cell, it can be passed down to the individual’s offspring. Once an acquired mutation is passed down, it is a hereditary mutation. Acquired mutations are not passed down if they occur in the somatic cells, meaning body cells other than sperm cells and egg cells.

Detailed explanation-4: -The sperm and egg pass from parents to their children, so the mutation is inherited. You can’t inherit somatic mutations because they occur randomly in cells that aren’t the sperm or egg.

Detailed explanation-5: -Germ-line mutations occur in reproductive cells (sperm or eggs) and are passed to an organism’s offspring during sexual reproduction. Somatic mutations occur in non-reproductive cells; they are passed to daughter cells during mitosis but not to offspring during sexual reproduction.
